BUTTON-ATTACHING MACHINE.

"I FECIPICATION forming part Of Letters Patent NO. $39,024:, dated March 30, 1886.

Application filed January 11, 1886. Serial No. 188,183. (No model.)

To rtZZ whom it may concern.-

Be it known that we, XVARREN G. SLATER and JEREMIAH LAMOREAUX, citizens of the United States, residing at Fremont, in the county of Newaygo, State of Michigan, have invented certain new and useful Improvements in Button-Attaching Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure 1 represents a side elevation of the right-hand side of our improved machine, part of the goose-neck of which is broken away to show clearly the stationary and removable button-feeder and fastener-feeder. Fig. 2 is a longitudinal section through the machine, taken in the vertical plane indicated by dotted line 00 x on Fig. 3. Fig. 3 is a front elevation of our improved machine. Fig. 4 is a detail view of the fastener-feeder. Fig. 5 shows one of the fasteners; and Fig. 6 is a view showing a button clinched to a piece of cloth or leather, as they appear after leaving the machine.

This invention relates to novel improvements on machines which are designed for automatically securing buttons having eyes to clothing or to boots and shoes; and it consists in certain novel improvements on such machinery, which improvements will be fully understood from the following description when taken in connection with the annexed drawings.

A designates the base of the machine,which is adapted to be secured upon a table, and B designates the main frame, from which rises a goose-neck, B, to the overhanging head B of which avertically-adjustable anvil-rod, B is secured by means of a binding screw, a. The lower tapered end of this anvil-rod has a concave depression in it adapted to receive the end of the button-fasteners b, and to turn or clinch them in the cloth or leather as represented by Fig. 6 of the drawings.

On the left-hand side of the frame B is a standard, 0, which is preferably shaped as represented in Figs. 1 and 2, and which is rigidly secured to said frame, so that it can be removed therefrom when desired, and on the left-hand side of the front portion of the frame B is a vertical post, 0', which is also removable, and between which and the frame B is a Vertical channel in which our improved feeder D receives a vertical reciprocating motion. The feeder proper is connected by a pitmanrod, D, to a treadle, (not shown in the drawings,) but which is located in a convenient position to the operator sitting at the table on which the machine is secured. The feeder D is a straight piece terminated at its upper end in a concave seat for the fasteners 11, and at its lower end in a V-shaped notch, as shown in Fig. 4. At the upper end, and secured to the front of the feeder D, is a spring-lip, e, which serves as a gage or stop to prevent the fasteners from passing too far after they are seated upon the feeder. To the rear side of this feeder D, near its upper end, is a tripping pin, (2, for a purpose hereinafter described. v

E indicates a long U-shaped spring, within which the feeder D is allowed endwise move ments. The upper ends of this spring E are bent inwardly, to form gripping-lips e e for the heads of the fasteners b. The feeder D receives its upward strokes from a treadle actuated by the foot of the operator. Now, the downward strokes of the feeder D are given to it by a spring, F, one arm of which is secured to the post 0, and the other end is secured to the feeder, as shown in Fig. 2. This spring F not only depresses the feeder after a fastener is clinched, but it also holds the lips e e of the U-shaped spring E down to its place on the head of a fastener, 12, while the latter is being clinched against the anvilrod B G designates the stationary section of the channeled fastener-feeder, and G a removable section thereof, connected to it by a sleeve or other suitable joint. These fastener-sections lie upon an inclined curved shelf, G, of the franie section O, and the upper or movable section, G, can be readily detached from the machine and filled with fasteners b when desired.

The lower or delivery end of thelower fixed section, G, is vertically and longitudinally slotted for the purpose of allowing freedom of vertical upward motion of a curved spring, H, which lies in the path of the lifting-pin d on the feeder D, and also in the path of a spring, which is secured to the bottom of the section G, and constructed with a checktongue, 9, that passes up freely through the bottom of the said section, and is held down out of the way of the fastener heads by its own spring 9. Directly in front of the checktongue is an arch, h, which crosses the grooved channel of the section G. The inclination of the fastener feeder is such that the fasteners descend to the work by their own gravity, and are arrested and successively discharged by giving vertical movements to the check-tongue g. These movements are alternately imparted to the check-tongue g by the pin d, acting on the spring H, and the spring 9 of the said tongue, as described. Above and on one side of a vertical plane intersecting the center of the inclined fastener-feeder sections G G are the feeder-sections J J for the buttons f, which are inclined on a curve for feeding by gravity, and constructed to receive freely the heads of the buttons, and to expose on the left-hand side the eyes of these buttons. The lower section, J of the button feeder is rigidly and permanently fixed to the frame 0, and the upper section, J, is removable for convenientlyfilling it when necessary. The lower or discharge end of the section J has a curved slot, i, continuous with the main slot, a short slot, j, having a spi'ingiongue, 7c, and a perforation, Z, forming a seat for the lowest button of the charge. The curved slot z'is designed to bring the eyes of the buttons about to receive the fasteners bin a horizontal plane, so that the points of the fasteners, as they are lifted by the feeder D, will with certainty pass through said eyes before said points impinge against the concave clinching end of the anvil-rod B After each clinching operation the cloth or shoe-leather, as the case may be, is drawn backward by the operator and a but ton extracted from the feeder J. The springtongue presses on the button f gently and aids during the operation of fastening it.

At the proper place for the terminus of the feeder D is a stop, 8, (shown in the sectional View of the annexed drawings,) and in this position of said feeder a short space is left between its upper end and the gripping-lips e e of the U-shaped spring, into which space the head of a fastener is received. Then at the commencement of the ascending stroke of the feeder D the fastener is gripped between its upper end and said lips and firmly held by the spring F. The feeder and U-shaped spring are then thrown up, and the point of the fastener,which has been previously passed through the cloth or leather, passes through the eye of a button and the fastener is clinched against the anvil-rod, thus completing the operation.

It will be seen from the above description and by reference to the annexed drawings that our machine is automatic in its operation, simple in construction, durable, and at the same time cheap to manufacture.

Having fully described our invention, what we claim, and desire to secure by Letters Patent, is

1. In a button-fastening machine, the combination, with the button and fastener feeders constructed as described, of the verticallymovable feeder D, provided with the stop 0, pin d,and notched lower end,and the U shaped vertically-movable spring provided with the inwardly-turned lips e e, the whole adapted to operate as shown and described.

2. In a button-fastening machine, the combination, with the vertically-movable feeder and its gripping-spring, of a spring stop-tongue on the front of and at the upper end of the said feeder, as and for the purpose described.

3. The combination, with the feeder and its gripping-spring actuated as described, of the pin d, the fastener-feeder, the spring checktongue, and the lifting-spring therefor arranged in the path of said spring, substantially as described.

4. In a button-fastening machine, the combination of the fastener-feeder and grippinglips with the inclined fastener-feeding trough and button-feeding trough and adjustable anvil-rod, substantially as described.

5. The fastenerfeeding trough and buttonfeeding trough, the former provided with the spring-stop g and the latter with the springtongue 70 and button-seat Z, and each having removable filling-sections, in combination with the feeder D and Operating mechanism therefor, substantially as described, and for the pur; pose set forth.

6. In abutton-fastening machine, an inclined slotted button-carrier provided with a curved slot, a spring-tongue, and aperforated buttonseat at its delivery end, substantially in the manner and for the purposes described.

7. In a button-fastening machine, the combination of the main frame, the button and fastener feeders, spring H, tongue 9, feeder D,

' having the V-shaped notch, pin d, and springstop 0, U-shaped lipped spring E, spring F, anvil B and pitman D, the whole adapted to operate in connection with one another, as shown and described.

In testimony whereof we affix our signatures in presence of two witnesses.
